Works fine but there is no documentation so I don't do it.

Works fine but no documentation so I don't know for example if the output is linear or how to convert readings to actual UV values. The output is low. With a 5V power supply, the maximum readings I got in sunlight were about 1/2V. The supposed variable amplifier doesn't seem to be working. Turning the potentiometer does not affect the readings.

Pros

Supports interrupt output, programmable high/low threshold

Cons

Hard to tell
